Claims.

My invention has to do with bath equipment and more especially withspray heads as used in shower baths, by operators in beauty parlors forshampooing, and the like.

Among the advantages of my improved spray head are the directing of thespray axially of the head and the confinement of the spray within arestricted area, its adaptation for secure and insurance against injuryto itself or chipping of the bath tub or bowl; and above all theremovability of the spray disk from its mounting within the head forcleaning the apertures from mineral deposits and other foreign matter,whereby to maintain a uniformity of flow and distribution in the spray.

In some localities the large content of lime and other minerals in thewater speedily form an incrustation in and about the apertures of thespray disk, particularly if small, as in a needle spray. Other foreignmatter also tends to clog the openings, obstructing the flow andrendering the spray non-uniform. The ordinary spray under strongpressure is prone also. to scatter or splash over a larger area than isdesirable. A shower or spray head of this general type, held in the handof an operator, especially when giving a shampoo, does not afford asecure grip against slipping, and it becomes uncomfortably hot at timesand the rubber tubing adjacent the spray head becomes not only hot butis liable to kink and break at the junction with the head, if notprovided with an enveloping heat-radiating handle. Moreover, the enamelof bath tubs and bowls is very often chipped by dropping into the same.These disadvantages are avoided and difliculties solved by thecharacteristic features of the present invention.

To facilitate an understanding of the invention, a preferred embodimentof the same is set forth by way of illustration in the accompanyingdrawing and in the following description predicated thereon.

In the drawing:

Fig. 1 is a side elevation of the spray head and the adjacentwater-supplying tube;

Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1; and

Fig. 3 is a front elevation of the spray head partially broken away.

Having particular reference to the drawing, the spray head generallyindicated at H is attached in the usual manner to a water-supply tubeE2, the end of which engages over the nipple I3 of the head. The headitself is of general flaring bell shape, preferably having its contourinterrupted by circumferential depressions indicated at M.Advantageously the head terminates forwardly in a cylindrical portion 15having aradially extending marginal flange IS. The junction of thecylindrical portion IS with the flaring portion of the head forms at I!a forwardly facing inner shoulder which serves as a seat for themetallic spray disk l8 provided with the small apertures I9. l

'A rubber ring 20 of general U-section embraces the forward portion ofthe head, the outer leg 2! of the U-shaped ring taking over the flangeI6 and closely hugging the outer face of the cylindrical portion l5 ofthe head, theouter curved surface of the ring forming a continuation of'the curvature of the flaring portion of the head and circumferentiallycorrugated as shown at 23. The inner leg 22 of the ring extends insideand closely hugs the cylindrical portion l5 with its terminal edgebearing rearwardly against the margin of the disk l8 out+ wardly beyondthe perforations 19, whereby the said spray disk is held firmly upon itsseat on the shoulder l1.

' It will thus be seen that if the apertures of the spray disk becomeclogged so as to interfere with the uniformity of the spray the rubberring 20 can be disengaged from the flange l6 and removed, freeing thedisk l8 which can then be lifted from its seat for the purpose ofbrushing and cleaning the rear face.

It will also be seen that the disposition of the inner leg 22 of thering with its face axially disposed relative to the head serves todirect the spray and to confine the same within a small area.

' corrugations provided upon the outer face of the rubber ring and thedepressed zones I4 of the head facilitate secure cupping of the samewithin the hand. The disposition of the rubber ring about the widestportion of the head prevents any contact of the head with the finish offurniture or the enamel of a bath tub if the spray should be dropped, asis often the case.

Manipulation of the head and the action of hot water tends to cause theWater-supply tube l2 to break or kink adjacent the head at the point ofits engagement with the nipple l3. The tube also becomes uncomfortablyhot at times causing discomfort to the hand of the operator. To meetthese conditions, I provide about the tube l3 adjacent and for aconsiderable distance from the head a handle of spirally woundheatradiating and kink-preventing wire as indicated at 24.

The term rubber is herein used in a generic sense to include equivalentsubstances such as other elastic deformable material. In theclassification of the head as bell-shaped is included any enlargedhollow body serving as a discharge manifold to increase the area of thespray over that of the supply tube or pipe. Neither is the invention tobe restricted to a portable or hand spray, as the head may form a partof a permanently installed bath fixture. Moreover, instead of the diskbeing removably held in place by a rubber or other elastic'ring,measureably satisfactory results may be obtained by other means forreleasably holding the disk in place within the head. Also, the spraydisk may be of other than metallic material such as vulcanized rubberequivalent for the purpose.

Generally speaking, it is to be understood that the detailed descriptionand illustration of a preferred form of the invention are to be taken inan illustrative rather than a limiting sense.

I claim: 7

1. A bell-shaped spray head providing an interior forwardly facing seatand terminating in a marginal flange, a perforated spray disk removablydisposed within the head upon said seat, a rubber ring removablyembracing the flanged margin of the head and projecting rearwardlywithin the head into abutment with the margin of the disk, whereby thedisk may be removed for cleansing.

2. A bell-shaped spray head providing an interior forwardly facing seatand terminating in a marginal radially extending flange, aperforatedmetallic spray disk removablydisposed within the head uponsaid seat, a rubber ring of general U-shape in section embracing theflanged margin with the outer leg taking over the flange and closelyhugging the outer face of the head and the inner leg lying closelyadjacent the inner face of the head and bearing rearwardly against themargin of the disk, whereby the disk may be removed for cleansing.

3. A bell-shaped spray head providing an interior forwardly facing seatand terminating in a marginal radially extending flange, a perforatedmetallic spray disk removably disposed within the head upon said seat, arubber ring of general U-shape in section embracing the flanged marginwith the outer leg taking over the flange and closely hugging the outerface of the head and the inner leg lying closely adjacent the inner faceof the head and bearing rearwardly against the margin of the disk, theouter leg of the rubber ring circumferentially corrugated and the outercontour of the bell-shaped head having depressed zones, whereby tofacilitate cupping of the head in the hand and to permit removal of thespray disk for cleansing.

4. A spray head of flaring bell shape terminating forwardly in asubstantially cylindrical portion with a marginal flange or head, theinner junction of the flaring and cylindrical portions providing aforwardly facing shoulder, a. perforated metallic spray disk seatedwithin the head on the shoulder, a rubber ring embracing the flangedmargin of the head and extending inwardly of the head to abut with itsedge the metallic spray disk, whereby to permit the removal of the diskfor cleansing.

5. A spray head of flaring bell shape terminating forwardly in asubstantially cylindrical portion with a marginal flange or bead, theinner junction of the flaring and cylindrical portions providing aforwardly facing shoulder, a perforated spray disk seated within thehead on the shoulder, an elastic ring embracing under tension theflanged margin of the head and extending inwardly of the head to abutwith its edge the spray disk, whereby to permit the removal of the diskfor cleansing.
